Osteoid osteomas are painful bone lesions that symptomatically respond to NSAIDs. Radiographs reveal a dense sclerotic cortex surrounding a small radiolucency or nidus. Symptoms often are worse at night and usually are not activity related. While treatment in the past has consisted of open en bloc excision, current means of removal include percutaneous drilling under CT guidance as described by Donahue et al and percutaneous radiofrequency ablation for extraspinal lesions as described by Rosenthal et al. Donahue et al demonstrated 100% successful nidus excision with CT guided percutanous drilling confirmed by postexcision CT, histologic evaluation, and absence of symptoms on clinical and radiographic followup. Success rates of percutaneous radiofrequency ablation are between 88% and 77% depending on defining failure by requiring revision or subjective outcome according to Rosenthal et al. Because the lesion is not caused by pyogenic organisms, antibiotics are not indicated.
